.TH PCRE2_JIT_STACK_CREATE 3 "24 March 2017" "PCRE2 10.30".SH NAMEPCRE2 - Perl-compatible regular expressions (revised API).SH SYNOPSIS.rs.sp.B #include <pcre2.h>.PP.nf.B pcre2_jit_stack *pcre2_jit_stack_create(size_t \fIstartsize\fP,.B " size_t \fImaxsize\fP, pcre2_general_context *\fIgcontext\fP);".fi..SH DESCRIPTION.rs.spThis function is used to create a stack for use by the code compiled by the JITcompiler. The first two arguments are a starting size for the stack, and amaximum size to which it is allowed to grow. The final argument is a generalcontext, for memory allocation functions, or NULL for standard memoryallocation. The result can be passed to the JIT run-time code by calling\fBpcre2_jit_stack_assign()\fP to associate the stack with a compiled pattern,which can then be processed by \fBpcre2_match()\fP or \fBpcre2_jit_match()\fP.A maximum stack size of 512KiB to 1MiB should be more than enough for anypattern. If the stack couldn't be allocated or the values passed were notreasonable, NULL will be returned. For more details, see the.\" HREF\fBpcre2jit\fP.\"page..PThere is a complete description of the PCRE2 native API in the.\" HREF\fBpcre2api\fP.\"page and a description of the POSIX API in the.\" HREF\fBpcre2posix\fP.\"page.
